Cisco Wireless :: To Do Up Or Down Threshold With NEC MH240
Jun 27, 2012
In WLC i see the roaming option to controller the handover. As the accompanying graph [URL], how do I up or down the threshold of the handover? or, How do I more sensitive to IP phone(NEC model MH240)?
I don't understand the four textfield of the roaming options URL
I need a WCS report that will actually give me the top n Wireless Access points that have too many clients trying to authenticte to them.We have some serious capacity issue in meeting rooms but we need a ball park figure of how many WAPs might be affected.
I know I can interogate the WCS to drill down and find out that WAPs are exceeding their threshold I just need to have a decent report generated.I have searched the reports from WCS 6.0.202.0 and cannot seem to find anything that suits.
I've read some opinions that lowering the RTS threshold can facilitate in some noisy wireless environments. I have found how this can be done on standalone APs but cant seem to implement the change on a WLC 2112. How to do it.
I set the Cisco's AP settings with MTU size as 1200 bytes and the Fragmentation threshold to 256 bytes. Set up: I am using a WiFi enabled laptop connected to Cisco AP running an application pumping data of size 1400 bytes continuously to a Wireless node connected to the same Cisco AP over WiFi.
I am monitoring network activity on the same laptop using Wire shark.However,i cannot see 1400 bytes data getting fragmented. What is the concept of fragmentation and MTU size? Also,I would like to know how to change the AP settings so that i can see the data (1400 bytes)getting fragmented to small byte chunks.
How to find out which Fault Threshold group a specific interface belongs to.The scenario is that in Fault Manager there is an alarm for which I want to change the Threshold Setting.
Example Alarm: Event_Description HighUtilization Device IP x.x.x.x Device Type Routers Fault Last Updated At 19-Mar-2013 09:44:25 Component IF-router2.x.x/26 [Tu187] [x.x.x.x] [Code] .....
I'm using RADIUS and FlexConnect APs. The issue is intermittently users will lose connectivity as if they're de-authenticated. Their clients still believe they're associated to wireless but they have no network connectivity. On Windows 7 we receive the exclamation point over the signal strength indicator.
There doesn’t seem to be any rhyme or reason as to what is causing this. It doesn’t seem to happen at any particular time intervals or anything else I can identify. Sometimes users will go entire days without experiencing connectivity issues sometimes they can’t go five minutes. When the clients are experiencing the issues they cannot even ping their default gateway.
The setup was initially the following:
Site A: 1142N APs and RADIUS server (server 2003) users are authenticating to.
Site B: Flex 7510 running code 7.0.116
Between site A and site B there is a site to site VPN with no restrictions.
After some time of working with TAC and not getting anywhere I setup the following:Site A: 4402 WLC running code 7.0.116 connected the same 1142N APs HREAP mode. I had the same issue with connectivity with that setup.Today I changed over to local mode and as of yet I haven’t had reports of connectivity issues.
When running ‘debug client MAC’ I see no indication of connectivity issues. I also have an NCS and I don’t see anything indicating what the issue is there as well. I’ve tried with both enabling and disabling ‘H-REAP Local Auth’. We seem to experience the issue in H-REAP standalone mode as well.
We're getting complaints about a specific 1131AG in the field only being intermittently accessible. WCS shows both the a and b/g interfaces randomly bouncing, sometimes the reason for the bounce is unknown other times it says it's because it lost connection to the controller. I can ssh into the WCS but the engineer who setup the AP's doesn't seem to have enabled remote access via telnet or ssh.
We are also seeing these events:
802.11a interface of AP * is down: Controller 172.17.0.10 Reason: Max retransmissions for the AP have reached.Interference threshold violation reported by '802.11b/g' interface of AP *, connected to Controller '172.17.0.10'.I know I can adjust the threshold percentage, but that would only seem to mask the issue.WCS gives this version info on the AP:

On a Cisco ASA 8.4 code is it possible to receive an alert once a certain number of tcp/udp connections is reached? I'd like to see if I can get an email alert or syslog if the ASA reaches say 2,000 connections for example. Once I get an alert I could then investigate the cause of so many connections.
I am working on a QoS design which I hope to test at some point, but at this stage its from the books.My question is how to decide which queue and threshold to use for video traffic, then lower priority traffic.I understand the shaping and sharing commands, its the queuing and threshold bit I'm not clear on.The plan is to use the priority-queue for EF marked voice, this will be policed on ingress to provide an upper limit to EF traffic levels, then my second priority traffic will be video. Which queue will get serviced first once the priority queue is empty, and how do I decide which threshold to allocate my video traffic to? The document ion is not at all clear, I want to prioritse my traffic in the following order:
1 voice, use the priority queue 2 video, this to get serviced ahead of data, after voice. 3 interactive data 4 Bulk data 5 Best effort
So Q1 settings are ignored due to priority queue. Q2 gets 70%, Q3 25% etc.Is it as simple as putting video into Q2 T1, then interactive data into Q2 T2, will Q2T1 get a higher priority over Q2 T2 once the PQ is serviced?
I have a switch where the current power threshold is set to -20.0db. The problem is that the receive power fluctuates between -19.9db to -20.1db, which is causing it to throw alarms on my solarwinds monitoring server. What I would like to do is change it to a different warning threshold, but I can't seem to find the command to do so. This is a catalyst 3750 running IOS version 12.2(55)SE3. [code]
I've already found this kinds of cases, in this community. So, It seems that Changing the current configuration to 'mls aging fast threshold ## time ## ' is most suitable in our situation.But, I don't know how to calculate the apt threshold value and time value.

I have an RV042 (it's old, silver/dark grey plastic front one) w/ firmware 1.3.13.02-tm.
The reason we bought this (long ago) was to balance two WAN connections, one with unlimited data and one capped monthly. It did that once, but for a couple years both connections have been unmetered so it's just been balancing them 50/50. As of today one WAN connection (the new much faster one) is back to being metered but I can't figure out how to configure the RV042 as it once was to prefer sending traffic over the slow, unmetered connection first, and only use the faster metered connection when necessary.
It's been a long time and honestly I only vaguely remember the ability to prioritize a connection based on % of bandwidth used so that all traffic would go over the unlimited connection 1st until it was flooded, and only then fall over to the metered connection. This is totally different than the weighted round robin, or smart link backup.
I found this 3rdparty forum post that supports that vauge memory and suggests this was eliminated between firmware 1.23 and 1.3: [URL] Is it possible to replicate this functionality with the current firmware? if so how? If not, how to do roll back to firmware 1.23?
It sounded like perhaps I could assigned WAN1 a bandwidth of 100000 (even though it's really 1500) and then assign WAN2 a bandwidth of 1 (even though it's really 20000) and the result might be the prioritization I'm looking to achieve... but I feel like I'm stumbling in the dark at the point.
One of my clients is using Cisco catalyst 2955 industrial switch.I am doing the configuration for them and come across one setting of FCS Error Hysterasis Threshold. I know FCS is Frame Check Sequence.
I do not understand is what is the meaning the setting of Hysteresis in term of percentage stand for what purpose?For example, the default is 10 percent. If I set the value to be lower 5% and what is the impact on that? Is this more stringent than default of 10% or less stringent than default of 10%?
Recently I faced 1 issue in MLS 6509.MLS had all Gig modules in slots 6,7,8 taking System detected CRC error rate on port ASIC data bus exceed fatal threshold, ("System detected CRC error rate on port ASIC data bus exceed fatal threshold".) causing the module reset by the SUP. After this active SUP causing it to failover the standby. This process was continuing every few minutes resulting in the SUPs on MLS rolling.what could be the issue for Sup rolling reset?
I have a Netgear WNR3500L wireless router. I assume it's v1 because on the back it doesn't have "v" anything. Firmware version V1.2.2.44_35.0.53NA.When I connect using g I get 22+Mbps download speed. When I connect using n I get 10 Mbps. I've tried using both WPA2 only (laptop reports 130 Mbps connection I believe) as well as the combo WPA+WPA2 (laptop reports connection of 117 Mbps).Broadband download results don't change - they stay at the 10 Mbps level. I've fiddled with some of the settings on my laptop's wireless card - but the results are the same.For now I'm just trying to figure out where I should focus my investigation and fiddling efforts - on the laptop or on the router.
i have a Netgear N600 Wireless ADSL2+ router on wireless a/b/g/n dual band and all that but what i want to know is will i get better performance if i use a WirelessN card over G on a 10 - 15mb/s connection gaming wise and will it b a great increase over the G causeif its not a HUGE increase then i wont waste my money on a newer card?
My Acer Aspire 5610Z laptop will automatically connect to public hotspot wireless network but when I attempt to connect to a wireless network at home, set up using a Netgear modem, I only ever get 'local' internet connection only. My wife's HP laptop has no problem making the home wireless connection.
I am running windows vista and have installed the software and windows sees the adapter and states it is working but when it searches for available networks it can't find any. How can I download the driver and install it?
I have a setup involving 3 clustered AP541 running off a sg300 switch. The wireless network setup VAP has one entry for vlan 1 with station isolation disabled. Is there anything more I need to do to allow one wireless client to ping another wireless client - am I missing something - i assume this is possible.Needless to say wireless clients can ping non wireless clients and vice versa quite happily. Everything is running with factory default settings more or less.

I have a WLC 5508, AIR-LAP1142N APs and a SSID for students to connect to who bring their own device. I am still testing this and it has not been rolled out but I am running into some serious issues with joining the network. I am authenticating them through a RADIUS server (2008 R2). Problem: many of them cannot connect because they are lacking the certificate.
1. What is a good setup for authentication in a BYOD environment
2. If my setup is good what can I do to allow kids to use their computers on the wireless either without the certificate (which I know is unlikely) or what do I need to have them do to connect. I am hoping it does not involve hard wiring and getting the certificate from the server.
have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. ted.
We have recently been given this unusual task. The setup is a series of CAP3502P access points, and a wireless controller (either 2500 Series or 5500 Series), as well as other standard network infrastructure.
In this network, the client (mobile/wireless) devices must be able to detect when they change what access point they are communicating through, while also requiring a seamless transition. Ie, if the client device is communicating via access point A, and displaying the application menus for A, when the user walks to the area services by access point B, it must detect that sot he application can display menus for B, without the user having to select "B".
Is there a way for the client device to detect which access point it is using and provide that to an application? Or alternatively a way for a host service residing on a server to get that information from the wireless controller?
i am placing a formal request to Cisco and to the firmware development team to create a new-and-improved firmware release for the WET200 wireless Ethernet bridge, a product that is still being produced, shipped, and sold. I purchased the product about one-and-a-half years ago and have enjoyed its performance. There have been, however, some flaws with the device, namely the following:While configured to use WPA2-based security, DHCP-related traffic is not passed from a router/gateway's DHCP Server to connected devices on the WET200. Current firmware release notes indicate this was a known issue and was, supposedly, fixed; however, due to the level of problems customers are reporting, it appears this may have only been resolved, if at all, with security configurations of WPA, WEP, or OPEN. It has not been fixed for customers using WPA2-based security.When I originally purchased the WET200 and configured it to use WPA2-based security, while it, initially, did have a few problems connecting to my router/gateway, it, eventually, did connect and stayed connected for, approximately, one year. However, in September of 2009, it suddenly lost connectivity with my router/gateway and has not been able to establish a connection since, even after reinstalling the latest firmware revision and after several soft and hard resets of the device. I tested the WET200 with another router/gateway, only to experience the same issue. Other devices are connecting to my router/gateway, but, not the WET200. The last firmware update for the WET200 was dated back in July of 2008. Currently, it is January 2010 and since these issues have been known for quite some time, it is unacceptable that the firmware for this device has not been updated in such a long time, especially when there are known issues with the WET200's firmware. Such lack of support is forcing me and my clients to stop using these Cisco-based products and purchase competing hardware, something I would prefer not to do; however, without better support, I and my clients do not have a choice. Expecting me and my clients to use an inferior form of security on the WET200, such as WEP and/or WPA, until a firmware update is issued is unacceptable, especially when that update has not been released in over one-and-a-half years. Such lack of support is especially unforgettable when my clients and I are looking to purchase new networking equipment. In the past, I would not have hesitated to purchase a Cisco-based product; now, with this experience in mind, I am finding it very difficult to recommend to a client that he or she should invest their organization's finances into Cisco-branded equipment. Proper, professional, timely, support of your hardware is expected of your customers, especially if you wish them to remain loyal customers. I have noticed that other similar devices, albeit, higher-end devices, have had their firmware updated, more recently, compared to the WET200. I assumed this meant that the firmware development team was updating all firmware on such devices. So far, I have been disappointed in the lack of firmware updates for the WET200. While I understand the possible desire to update the higher-end products, first, as a professional whose job is to research, recommend, purchase, install,configure, secure, and maintain both the enterprise-level and small business-level devices, I highly encourage Cisco not to overlook their small business products when the firmware development team is updating firmware for any Cisco products. Deficiency in the support of one strata of Cisco-based products is reflective upon the support of any Cisco-based product and is not easily forgiven by Cisco customers, such as myself, when new and additional hardware needs to be purchased.
WET546 successfully authenticates and looks pretty healthy on controller (see below) , however neither of computers plugged to WET546 was unable to obtain ip address from dhcp server , nor working with static ip. I was under impression what it might be related to some default policies on WLC2100. Logs (warning) on WLC2100 looks clean.
This is the first time I am trying my hands on wireless gears. I have 2500 WLC and 1142 AP (which I converted from Standalone to LAP).I have a layer 3 POE switch where i am using port 1 for the WLC which is a trunk port.
Port 2 is for the AP using access vlan 111
Port 3 is trunk port going to a router where i am running dhcp server for the VLANs which are as follow:
I wanted to block the traffic from the Guest VLAN 999 but when i apply the ACL on the Guest Interface created on the WLC, I dont see any pings going across and neither I see any hit counts on the deny statement as if the ACL is never applied.
I just read that starting from version 7.4, the 2500 controller can be used to terminate guest anchor tunnels. have a question regarding the performance of the internal DHCP server when used in guest environments.
We have a 2504 Wireless Controller and it works great!We currently have 6 Access Points (Aironet 1252) connected.We just added the sixth one a few weeks ago and with a properly configured and fully functioning Wireless Controller, it was super easy.Now, I have been assigned to add another Access Point, but at a remote site.The plan is to have up to three or more APs at this remote location and we want them to talk back to the Wireless Controller.We have plenty of licences on our current Wireless Controller.Do do not want to spend the funds for another Wireless Controller and more licenses.
1. How does one manually add a Aironet 1252 to the 2504 Wireless Controller
2. If the AP is on a different subnet than the Wireless Controller, how does one get it registered?
3. The best for last: Can a Aironet 1252 talk to a 2504 Wireless Controller over a WAN link?
Android users can connect to our hospital guest wireless but will not have connectivity. Our wireless infrastructure is WISM based with 2 controllers on 6509 platform. We have a mixed environment of 1231, 1252 & 3502 series APs.
Had issue connecting just Android devices? All other devices connect fine.
I have problem setting up wireless repeater using Cisco 1242AG access points. Here is the setup and problem - The location has 2 1242AG APs and a WLC (2206) which will be used by PDAs. One of the AP was converted to Lightweight AP and is wired. This AP is up and working and PDAs are able to connect to it. There is 1 WLAN and it uses Local EAP (LEAP) as authentication. Layer-2 security is configured as WPA/WPA-2 with 802.1X authentication. Under AAA servers Local-EAP is enabled and a profile (with LEAP enabled) is used. Local users are configured for login. As said PDAs are able to connect and it is working without any problem.
WLC (LEAP with local users) -----> LAP ----> Repeater AP
But the 2nd AP has to be configured as repeater was configured to repeater mode (refering to the document) and was placed. The WLC can see a client (with APs MAC address) but it is probing. The AP is still Automonous AP. Also username and password is configured for authentication. But still the radio on the AP is not up and it is in reset state.
Is 802.11ac wireless module for Cisco Access Point 3602 is available to order ? what Wireless controller we need to use for the support of 802.11ac wireless standard ?802.11ac will support only on 5700 series wireless controller ? Or it will support with 5508 Series also ?
We plan on buying a Cisco 2700 wireless location appliance but I need to know if it will be compatible with our 2500 WLC.I've tried to look but cant find any document for this. Also can you deploy the location appliance without a WCS?
